With the newly developed WRD Toolbox, we offer developers of wireless IoT applications various tools for debugging, end-to-end testing and monitoring with telemetry data for all relevant application components.

The modular function blocks of the WRD Toolbox enable comprehensive field tests in real application environments.

The Challenge

Anyone who has been involved in the development of complex embedded systems software knows the challenge: all individual components were subjected to a unit test, the interaction was ensured by integration and functional tests and finally a comprehensive system test was successfully carried out.

Nevertheless, some assemblies with the new software fail immediately after the first delivery to customers. And the causes are actually also known: After all, the aforementioned tests were carried out in the development environment and in special test laboratories.

However, the environmental conditions and, in particular, possible interference variables in a real application environment are often completely different – especially when wireless functions and battery operation are used, numerous surprises are to be expected. Added to this is the unpredictable “creativity” of the end user and the resulting interaction sequences.

A typical question in this context is therefore: How do we determine the detailed causes of each individual failure and what software changes are required to prevent such failures?

This example is about enabling a developer to remotely access the SWD-based debug interface of an embedded system as a target device from any location in order to test and, if necessary, modify the firmware of a wireless IoT sensor system

directly on site in an application environment from a workstation using VSCode or Eclipse.
The WRD/Probe has an internal LiPo battery and an LTE-M internet connection and can therefore be used anywhere.

WRD/Box: Wireless Remote Testing and Monitoring

The second example involves a long-term runtime test of an MCU module that is being developed for digitalization tasks with production machines. Vibration (IMU) data is recorded, prepared using sensor data pre-processing and then classified using Edge AI software – in other words, an AI-based soft sensor application.

One challenge here is the unfavorable environmental conditions due to various disturbance variables.

For this reason, continuous operation is monitored using suitable telemetry data, which is generated by a WRD/Box and sent via a 4G mobile connection.
